It is often said that power corrupts. But, it is equally important to realize that weakness corrupts too! Power corrupts the few, while weakness corrupts the many. Hatred, malice, rudeness, intolerance, and suspicion are faults of the weak. Resentment on the part of the weak springs not from injustice done to them, but from their own sense of inadequacy and impotence.

— Eric Hoffer, 1980
